Advanced Control Systems helps utilities modernize substation control centers with efficient and cost-effective remote terminal unit (RTU) upgrades. Continuing a 24-year tradition of upgrading third-party legacy RTUs, ACS has announced the new NTX-U57 upgrade solution for the Telegyr TG5700.
"We're proud of the innovation that has gone into the design of the NTX-U57, which gives the many utilities with TG5700s the ability to easily replace the I/O modules and deliver the advanced functionality of ACS' intelligent substation control," says Rob Sadler, ACS Director of Product Management. "This design is based on the same concept used with our very successful NTX-U20 upgrade for the aging Westronic/Harris/GE D20, now being used by several major North American utilities."
The ACS legacy RTU upgrade solutions address the concerns of utilities faced with the need to replace legacy substation RTUs to enable intelligent control and support modern communication protocols. By allowing the utility to leave all wiring, I/O terminations, and control relays untouched, the NTX-U57 and NTX-U20 solutions have delivered up to 60 percent savings over the cost of a full replacement. The TG5700 station manager (main processor) can be replaced with the ACS NTX-200 series controller to provide the Ethernet interfaces to the master and to each of the upgraded I/O modules. The ACS NTX Explorer tool is used to configure both the NTX-200 host and the NTX-U57 modules, simplifying management of the total upgrade solution.
"This is yet another example of ways that ACS is helping utilities to modernize their aging infrastructure to address 21st century challenges, such as NERC CIP compliance and the proliferation of digital data available from the substation," says ACS CEO Kevin Sullivan.
